It is widely used in a variety of special filtration conditions such as high impurity content, viscous liquid, ultra-high precision, etc.
Automatic Candle Filter It has the advantages of closed operation, large filter area, high dirt treatment capacity, easy to back-blow filter cake. The filter five functions: direct filtration, pre-coating filtration, slurry concentration, filter cake recovery, filter cake washing.
Working Principle
Closed candle filter is a combination of filter which combines several filter elements in a closed container to filter cloth (or other filter media) on the outer casing of the filter element. During filtration, the material feeds into the filter by a pump. During filtration, the material passes through the filter medium and enters the center of the filter element and is discharged at the outlet of the cleaner solution. Before forming a filter cake on the candle element of the filter, the material needs to be circulated and filtered. Until a certain thickness of filter cake is formed on the candle core, the cycle filtration is over and the normal filtration begins.
After the filter operates normally for a period of time, when the filter cake on the candle core reaches a certain thickness, the PLC sends the command signal to control the feed (stop). Then drains the residue in the filter. After draining, the PLC signal controls the back-blowing port (compressed air, nitrogen or saturated steam) to blow the filter cake off, after which the filter discharge port is opened for slag discharge. After the slag discharge, close the slag discharge outlet and return to the initial state before filtration, ready for the next round of filtration.
Features
It can be directly filtered, pre-coated filtered, slurry concentrated, filter cake recycled and washed.
